Descaling brush with particles of high hardness and rigidity and methods for manufacture

ABSTRACT

A descaling brush has a handle; a plurality of bristles formed on the handle; and fine particles fixed at distal ends of the bristles. The fine particles are made of high hardness and rigidity material such as diamond, CBN, Aluminum Oxide, or Silicon carbide.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is related to a descaling brush, and moreparticularly to a descaling brush with particles of high hardness andrigidity.

[0003] 2. Description of Related Art

[0004] Descaling brushes are used for removing rust or dirt, and arevery useful on smooth surfaces, but not so on rough surfaces becausedistal ends of bristles of the brushes are unable to effectively touchhollow areas. Furthermore, because the bristles of these descalingbrushes are made of wires such as iron wire or copper wire, which arenot sufficiently durable, none of the conventional descaling brushes hasa long useful life.

[0005] Therefore, the invention provides a descaling brush to mitigateand/or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

[0006] The main objective of the present invention is to provide adescaling brush with particles of high hardness and rigidity.

[0007] Another objective of the present invention is to provide a methodto manufacture the descaling brush.

[0008] Other objects, advantages and novel features of the inventionwill become more apparent from the following detailed description whentaken in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009]FIG. 1 is a perspective view of a first embodiment of a descalingbrush in accordance with the invention;

[0010]FIG. 2 is perspective view of a second embodiment of the descalingbrush of the invention; and

[0011]FIG. 3 is an enlarged partial schematic view of the descalingbrush.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] Referring to FIGS. 1 and 2, a descaling brush in accordance withthe invention is composed of a handle (10) and a plurality of bristles(11) embedded in the handle (10). In a first embodiment shown in FIG. 1,the handle (10) is cylindrical, and the bristles (11) are radiallyembedded in a periphery of the handle (10). In a second embodiment shownin FIG. 2, the handle (10) is flat, and the bristles (11) are embeddedas a phalanx on a first surface of the handle (10).

[0013] The bristles (11) are shown in FIG. 3. Each of the bristles (11)has a plurality of fine particles (12) of high hardness and rigidityformed on a distal end thereof. The particles (12) are available indiamond, Cubic Boron Nitride(CBN), Aluminum Oxide, Silicon Carbide andetc. The sizes of the particles (12) are preferable of between 20-400meshes per square inch.

[0014] According to the present invention, a process of manufacturingthe descaling brush includes following steps:

[0015] 1. Fixing the particles (12) such as diamond, CBN, AluminumOxide, Silicon Carbide on the distal ends of the bristles (11).

[0016] 2. Embedding the bristles (11) in the handle (10).

[0017] Fixing the particles (12) can be accomplished by one of themanners described hereinafter.

[0018] In a first manner, the process includes:

[0019] 1. Adhering the particles (12) on the distal ends of the bristles(11) by adhesive, and sprinkling solder on the particles (12);

[0020] 2. Drying and dewaxing the bristles (11) with the particles (12);

[0021] 3. Heating in a vacuum furnace the bristles (11) with theparticles (12) to melt the solder, and then the particles (12) are fixedon the bristles (11) when the solder cools down and solidifies.

[0022] The solder is preferably a metal solder including 1% titanium orchromium.

[0023] In a second manner, the process includes:

[0024] 1. Dipping the bristles (11) in an electroplating bath with theparticles (12);

[0025] 2. Electrification to reduce nickel in the electroplating bath toadhere to the bristles (11), and then the particles (12) are fixed onbristles (11).

[0026] In a third manner, the process includes:

[0027] 1. Adhering the particles (12) on the distal ends of the bristles(11) by adhesive, and spreading with resin;

[0028] 2. Heating in a furnace and then the particles (12) are fixed onthe bristles (11) when the resin hardens.

[0029] From the above description, it is noted that the invention hasthe following advantages:

[0030] 1. Because the distal ends of the bristles (11) each have a lotof fine particles (12) which are able to effectively touch hollow areas,the descaling brush is also useful on a rough surface.

[0031] 2. Because the particles (12) are made of high hardness material,the descaling brush has a long useful life.

[0032] It is to be understood, however, that even though numerouscharacteristics and advantages of the present invention have been setforth in the foregoing description, together with details of thestructure and function of the invention, the disclosure is illustrativeonly, and changes may be made in detail, especially in matters of shape,size, and arrangement of parts within the principles of the invention tothe full extent indicated by the broad general meaning of the terms inwhich the appended claims are expressed.
